Abstract

The invention provides a linear compressor with the adjustable air cylinder volume and a control method of the linear compressor. The linear compressor with the adjustable air cylinder volume comprises a shell, a stator, a main coil, a piston, an air cylinder, a rotor, a spring and a rear baffle, wherein the stator, the main coil, the piston, the air cylinder, the rotor, the spring and the rear baffle are arranged in the shell, and the rotor is provided with a permanent magnet. The linear compressor is characterized in that the rotor is further provided with an auxiliary coil, the auxiliary coil is used for selectively overlaying or counteracting the intensity of a magnetic field produced by the main coil, and the efficiency and reliability of the linear compressor are improved.

Description

technical field [0001] The invention relates to a compressor, in particular to a linear compressor with an adjustable cylinder volume and a control method thereof. Background technique [0002] At present, there are two types of compressors used in refrigeration equipment, rotary and linear. The linear compressors in the prior art usually include shells, stators, main coils, movers, pistons, cylinders, tailgates and springs. ; Wherein, the mover is provided with a magnet, the magnet is inserted in the magnetic field space formed by the stator, the main coil is placed in the stator, one end of the piston is connected to the mover, and the head of the piston is slidably arranged in the inner cavity of the cylinder , the shell is also provided with a suction tube. Chinese Patent No. 2009100769408 discloses a constant clearance device for variable capacity adjustment of a linear compressor, which uses an actuator to adjust the position of the exhaust plug to change the volume o...
